The output of top of the line geothermal sites already produce about what the top of the line fission reactors do (~1600MWe) - The setup of 1300~ MW tidal plants is already underway - and while solar is slightly lagging in scale (about 250MW plants atm) total output over the '11-'12 year increased by 60%... at that rate we'll be making a dent in things and quickly. Yeah fusion is just like - unlimited power - on our scale. But we don't have to be totally helplessly dependent on coal/dirty power up to that point.




I always wondered why no one harvested the energy of volcanoes

Didn't even know it was being done, but it seems logical

It is thermal energy we harvest if we do coal, nuclear reactors ,.... (since the heat drives a turbine)

so why not volcanoes too?

free energy in great amounts likely, due to lots of heat

Geothermal is not volcanoes.  You dig a hole in the ground and you can exploit any temperature difference to extract energy. 

I am not aware of any serious geothermal sources of major energy.  Perhaps twighead would be so kind as to give a link.......

There's a link to the largest complex right now.

Basically - its just dropping water into a naturally superheated reservoir - then collecting the steam created in the turbine etc.

I honestly think there is no stopping globalization and the eventual demise of our planet due to over development.

Why would the planet give a shit? It's gone through being a ball of magma, a giant iceball - for millions of years at a time - even if our challenge was to eradicate all the life on the planet we would struggle thoroughly with that - destroying the planet entirely aside. No. You mean - OUR demise. Not the planets.

Yep, it's really how livable the planet will be for us that's the issue. Doubtless many other life forms will go extinct, but that's nothing new.

Yep.  In the beginning oxygen was poisonous to life on earth.

saying it is a lost cause would mean nothing, get on your bike and lets sort this mess!

wouldn't it be great if a thousand years in the future we are being awarded for being passionate about all forms of life!

Yes, though that's not at all necessary. Remove subsidies from all energy sources in the US, and renewables actually gain an advantage. Government needs to divest from the energy sector altogether, imo. Obama isn't an investment genius, I'd rather not have him making decisions on which companies to throw money at...A123 and Solyndra have been evidence of that.

So you like great big giant batteries full of toxic metals and chemicals?  Solar is a dead end.  Wind chops up millions and millions of birds.  geothermal is good for heating and cooling.

We are fucked as a civilization if we do not develop fusion.  It is as simple as that.  Fossil fuels will run out some day although not any time soon.  Uranium will run out with the same caveat.  The other stuff has no chance of ever replacing them in any meaningful way.  We probably have about century to make fusion work on a large enough scale.  That is the only solar power worth a wank.  The scientific sun.

You may want to do some research on the direction that battery research is going if that's your perception of batteries. Furthermore, lithium batteries are recyclable, so the use of batteries doesn't create a perpetual demand of resources as other fuels do. I suppose your logic on why solar installations continue to grow at 30+% yearly is what, subsidy money? 1300-2000W/m^2 is a silly amount of energy to be so readily available, suggesting that it's a dead end is pure nonsense, especially given that the benefits of production can go directly to the consumer.

Proves my point even more, in July they broke 5.1TWh for the month. Watch how quickly that number grows going forward. We have to start somewhere, this situation didn't create itself overnight, and it won't fix itself overnight. We can't simply cross our fingers and say fuck it, drill, drill, drill and hope fusion is practical in time.

So, plants and animals die, what are you planning to eat? Food from greenhouses surrounded by a barren wasteland? The Thunderdome was cool and all, but fuck that shit. All for the sake of the continuation of something as pathetic as human beings? Where is the logic here?

You should read The world Inside.  it tells a story of how the human race was able to over populate yet still leave most of the planet for farming. 

and at the end, the question arises, was it the right choice? And the fact that regardless of what we choose, life will go on, at least among society, as long as it can.

Solar will cut energy dependency significantly in the future when the technology advances. Not only photovoltaic cells becoming cheaper but solar thermal energy as well. Especially in hot sunny places like in the southwest. Every house should have solar panels in the future. Solar is not sufficient when it is centralized. There's also solar paint which is being developed that can harvest solar energy. It's not the sole solution but it will help. Battery technology will also advance and it will allow electric cars to become more prominent. We need faster charging and higher capacity batteries. Electric motors are far more efficient than combustion engines.

I live in phoenix by the way and I personally know someone who basically has their entire roof covered in solar panels. It creates so much energy that he doesn't even use it all and he makes money selling energy into the grid.

Stanford Scientists Use 'Wired Microbes' To Generate Electricity From Sewage

They use wastewater to produce electricity, i saw a similar experience that is working here in Quebec in a larger scale. Standford use wastewater, Quebec use porcine dejections. What is interesting of those "biobattery" is their yield of electricity production.

Quote:

The Stanford engineers estimate that the microbial battery can extract about 30 percent of the potential energy locked in wastewater. That is roughly the same efficiency at which the best commercially available solar cells convert sunlight into electricity.

Of course, there is far less energy potential in wastewater. Even so, the inventors say the microbial battery is worth pursuing because it could offset some of the electricity now use to treat wastewater. That use currently accounts for about three percent of the total electrical load in developed nations. Most of this electricity goes toward pumping air into wastewater at conventional treatment plants where ordinary bacteria use oxygen in the course of digestion, just like humans and other animals.

Looking ahead, the Stanford engineers say their biggest challenge will be finding a cheap but efficient material for the positive node.

"We demonstrated the principle using silver oxide, but silver is too expensive for use at large scale," said Cui, an associate professor of materials science and engineering, who is also affiliated with the SLAC National Accelerator Laboratory. "Though the search is underway for a more practical material, finding a substitute will take time."




See, another way to turn something that is disregarded (waste) into valuable ressources
